margin is set with small tubercles. The outline of the large hand and 
the prehensile edges of the fingers are as in the preceding species. 
The ambulatory legs are relatively stouter. The dactyls are very much 
wider, and the inner surfaces are concave and spinulose. 
Color of alcoholic specimens light ochre. 
Alaska. 
Eupagurus curagaoensis. 
Anterior portion of carapace a little longer than wide. Median pro- 
jection produced, sharp ; lateral projections rounded. Eye-stalks stout, 
flattened, dilated at the cornee. Acicles much longer than the eyes. 
External spine of antennz reaching the base of the cornea. Flagella 
very slender, reaching the end of the large cheliped. 
Merus of large cheliped trigonal, very convex; upper and outer face 
Squamose; lower external angle spinulose. Upper surface of carpus 
subtriangular, granular; inner portion with a few scattered minute 
spines; middle and outer portions with scattered tubercles in bunches 
of two or three arranged transversely; the outer margin is slightly 
raised and inconspicuously tuberculose; the inner margin is thin and 
serrate. The hand is thin and wide, evenly and minutely granulate; 
the edges are thin and slightly upturned and crenulate. The upper 
surface of the dacty] is divided by a ridge running from the tip to the 
articulating condyle. 
Left cheliped much smaller than the right. Carpus flattened on top ; 
margins spiny. Hand with a thin elevated ridge running from the end 
of the pollex to the wrist, making a deeply concave subtriangular outer 
face. 
Ambulatory legs compressed. Upper margins of carpal and propodal 
joints sharp and spiny. Dactyls very thin, wide, bent and twisted. 
Color of ambulatory legs in alcohol. Meral, carpal and propodal 
joints light red with wide band of light in the center of each. Distal 
half of the dactyl reddish; proximal ialf, light. 
This species is closely related to H. carneus Pocock (Ann. and Mag. 
of Nat. Hist., vol. Iv, No. 24, 1889). 
Eupagurus californiensis. 
Anterior portion of carapace about as broad as long. Median projec- 
tion of the front sharp, in advance of the short angular lateral projec- 
tions. Eye-stalks moderately long and slender. Scales long, pointed, 
concave. The acicles of the antennz reach the ends of the eye-stalks. - 
Merus of large cheliped trihedral, smooth. Surface of the carpus 
Subtriangular; inner margin set with two or three spines on its distal 
portion ; behind these are one or two tubercles; outer margin slightly 
raised and a little uneven. The hand is much broader than the carpus. 
The palm is slightly granulose under the lens. The pollex is roughened 
by a few large granules. The outer margin of the dactyl is armed with 
comparatively large, blunt teeth. Part way between this border and
